This invention refers to a wash arrangement comprising at least one basin or trough of any desired length, but preferably of such a dimension that a plurality of persons can wash simultaneously their hands or their figures. More especially my invention contemplates a wash basin or trough provided with a channel of suitable lateral dimension at the lowermost part of the basin and preferably near to its rear wall, for the purpose to collect the dirty water and to lead it off to an outflow which is situated at a suitable point of the trough. According to my invention the rear wall of the trough is provided with a lengthwise extending projection which is adapted to cover the channel against sight of the persons using the arrangement, but leaving a lateral slot wide enough to introduce cleaning means for instance a brush to clean the channel from time to time. For this purpose the projection is arranged at the rear wall and vertically above the channel in a suitable space say 1" to 1 from the upper level of the channel, and is so dimensioned that the projection corresponds in breadth substantially to the width of the channel, but preferably extends slightly beyond the front edge of the channel.

Whilst in the known arrangements of the kind referred to the dirty water flowing off along the bottom of the basin hardly offers an aesthetical aspect for the user, in the new arrangement the channel is closed for the sight of the user.

By suitable dimension of the breadth of the projection the channel may be inspected by a person standing some steps off the front wall of the trough.

My invention may be easily understood by the annexed drawings of which Fig. 1 is a sectional view of one mode of performance showing a single-sided arrangement,

Fig. 2 is a sectional view of another mode of performance showing a double-sided arrangement,

Fig. 3 to Fig. 6 show sectional views in part of further modes of performance of double-sided arrangements,

Figs. 7 to 8 show details in section, and

Fig. 9 is a sectional view of a single-sided arrangement with further details, which will be dewards the channel 2 which is provided at a suitable place, preferably at one of its ends with the outflow I. Adjacent to the rear wall 6 and vertically above the channel 2 there is provided a fillet [5 of L-shaped cross section. The top part l6 of this fillet extends horizontally over the rear wall 6 into the brick-work, and increases in thickness towards its end to ensure like a wedge a safe connection with the brickwork. For this purpose the upper surface I! of the horizontal part is oblique, but, as shown in dotted lines, the lower surface may also be oblique.

The vertical part of the fillet has a nose-like cross-section and leaves a slot between the main part of the basin and the channel.

The water comes from sprinklers (not shown) fed and arranged in known manner at suitable height above the trough.

Bores 20 in the vertical part of the L-shaped member I5 are provided for the drops which often trickle from closed water taps. In the horizontal part l6 of that member, the inclined surface I! forms a receptacle for soap etc. The brick-work I2 around the trough is covered by tiles I9.

Arrow .1: corresponds to the sight of a user standing directly before the trough and leaning over it; it is easy to see that the user cannot see the interior of the channel, while the arrow y corresponding to the sight of a person who stands apart from the trough penetrates into the channel 2. In this way objects fallen into the channel can be discovered and removed.

The trough I may also be arranged on a frame of wood, metal or another material, of suitable height, and fixed by screws, clamps or the like. When the trough is so arranged at the frame that its upper edge is about at the same level as the uppermost point of the frame, the part [6 of the fillet I5 may be fixed at the rearside of the frame for which purpose it may have the cross-section of a clamp.

The trough and the fillet may consist of any desired material for instance of cast iron, sheet metal, natural or artificial stone, concrete, porcelain, stone ware, glass or thermoplastics; glaced tiles may also be used to line the surface of these materials.

Fig. 2 shows a double-sided arrangement with two parallel troughs I spaced apart and symmetrically arranged. Both the troughs are fixed on a suitable frame I4. In this performance the fillet is of clamp-like cross-section, and clamps together the two rear-walls 6 by its vertical parts 3, 3', while its horizontal part 4 covers the upper edges of the rear walls and the interstice between them. The channels 2, 2' in each of the troughs l' have any desired, but preferably a rectangular cross-section and are provided with outflow tubes 1 and 1' respectively. The channels may be slightly inclined towards the outflows. The vertical parts 3, 3' of the fillet have a nose-like cross-section and cover the interior of the channels against sight of the user, but leave lateral slots whereby the waste water can pass from the trough I or I into the channel 2 or 2'. Bores 5 may again be provided for the drops of trickling taps.

As to Fig. 3, the projection 8 forms a continuation of the rear wall 6 so that the trough and the projection consist in a single piece. An upper plate 9 joining the upward extending part 3 covers the space behind the rear wall 6.

Fig. 4 shows an arrangement in which the fillet is a separate member; its vertical part l rests on the bottom Ia of the trough by supports ll;

these supports are spaced apart and leave slots of suitable length between the main part of the trough and the channel 2.

Figs. to 9 show arrangements in which the basins and/or their accessories are composed or lined by single elements for instance plates, tiles or blocks.

As to Fig. 5 the trough is arranged on a standard 2| made of concrete and covered at the front side by tiles 22. The front Wall of the standard extends upward and forms an inclined front wall 23 of the trough which may be reinforced by iron rods 24. At the lowermost part of the trough and adjacent to its rear wall 26 there is arranged the channel 25 which may be slightly inclined towards the outflow tube 21. The channel 25 forms a separate block-like element; The bottom of the trough and its inside front wall are formed by plates or tiles 28 and 29 respectively. The upper front edge is covered by narrow tiles 30.

Above the rear wall 26 of the channel 25 a projection is arranged, which is lined by means of one or more horizontal plates 3|, an oblique plate or plates 32 and a horizontal top plate or plates 33. The plate or plates 3| may be connected to the standard 2|, and are so located and dimensioned, that the channel 25 is entirely covered in vertical direction, whilst a lateral slot is left free for the entrance of the waste water or of a cleaning device.

Again the arrows a: and y show respectively the direction of sight of a user and of a person standing apart from the trough.

The arrangement according to Fig. 6 shows a construction in which the front wall 35a and the bottom 35 of the trough as well as the channel with its rear wall 26 and its cover plate 34 are made of a single piece. A further part or block 36 of angular section joins with the front. edge of part 34 and forms a projection. The trough is placed on the standard 2| and is provided with the outflow tube 21.

Figs. 5 and 6 refer to double-side arrangements, whose symmetrical part is omitted for the channels are formed by a block 39 of T-' shaped cross-section, and are covered by a single plate 40 attached to the middle piece.

Fig. 9 shows a single-sided arrangement in which the trough 44 is supported by a standard 4|, and attached by suitable means to a wall 42 of brick-work, wood or the like. The front side of the standard and of the trough is lined with tiles 43. The bottom and the front wall of the trough consist of concrete and are reinforced by iron rods 45 which are arranged lengthwise and across. The channel 46 and the cover-plate 48 form a single piece with a rearward prolongation 49 which may be fixed by suitable means in the wall 42. The oblique surface 58 joining with the end of the projection 48, and a substantially horizonal or slightly inclined upper surface 5| are lined with tiles; wall 42 above the surface 5| is also lined with tiles.

The shown arrangements are merely examples and are not limitative, but may be varied at will without deviating from the inventive idea.

What I claim is:

1. A Wash arrangement comprising at least one trough, a channel at the lowermost part of said trough with an entrance opening throughout its full length and arranged wholly above the bottom of the trough, and a projection arranged above said channel and adapted to cover the interior of the channel against sight of the user..

2. A wash arrangement according to claim 1 in which the projection extends in horizontal direction wholly above the bottom of the trough and slightly beyond the front edge of the channel.

3. A wash arrangement comprising at least one trough, a channel at the lowermost'part of the trough and open throughout its full'length to the trough and a projection at the rear wall of the trough, said projection being vertically spaced apart from said channel and having a. noseshaped cross-section and extending horizontally slightly beyond the front edge of the channel.

4. A wash arrangement comprising at least two troughs, a channel at the lowermost part of and open throughout its full length to each of said troughs, a projection at the rear-wall of each trough vertically spaced apart from said channel, said projection having a nose-shaped cross section and extending horizontally slightly beyond the front edge of the channel, and. bores in said projection to permit passage of drippings from the trough-supply source directly'to the channels.
